Konta and Watson both won their singles matches as Britain saw off Portugal 3-0 on Wednesday, and the pair were triumphant again on Friday against host nation Estonia in Tallinn.

After Watson had thrashed 15-year-old Katriin Saar 6-1 6-1 in just 57 minutes first up, Konta eventually emerged victorious in a much-tougher encounter with world number 27 Anett Kontaveit to earn Britain an unassailable 2-0 lead in the tie.
